Do you have any errors in Xorg.0.log?  Also, did you add an 'AGPSize' option 
to your Xorg config file to tell it you have a 64MB aperture?  X seems to 
assume a default size of 8MB unless you explicitly tell it you have more.

The AGPSize is just to say how much of the aperture to allocate and bind
for use.  It turns out that 8MB is all that's really necessary, due to
poor or nonexistent use of AGP textures, so that basically what gets
used in AGP are the 3MB of vertex/indirect/ring buffers.

I wasn't previously aware of any 64-bit issues in the Radeon/R200 DRI
(and some have used these on 64-bit machines before), but to me that
seems like the most likely reason to find bad command buffers.

$ grep EE /var/log/Xorg.0.log
        (WW) warning, (EE) error, (NI) not
implemented, (??) unknown.
(II) Loading extension MIT-SCREEN-SAVER
Nothing unusual here.

I also added the following to xorg.conf.
    Option "AGPSize" "64"

DRI still loads, and rendering still fails with same
error.

Well, I have tried playing with all X Options for AGP, tried changing BIOS
settings, to no effect.

Today I borrowed an ATI Radeon QY RV100 7000/VE and have the same error from
any program trying to use DRI:
drmCommandWrite: -22
drmRadeonCmdBuffer: -22 (exiting)

Now I really am starting to think that it is a 64-bit issue.

Any suggestions?
